Ford Explorer Sport Trac Worn Timing Chain Cassettes May Cause Rattling Noise From Engine

(18 reports)

A rattling noise from the engine may indicate that the timing chain cassette is worn. Our technicians tell us that installing an updated cassette and timing chain tensioner should correct this concern.

Went through total of 3. yes 3. 2006 it caused a valve to set on top of piston. Got a rebuilt motor it ran 1 year. the only way shop would cover said problem, under warranty. was put on(all) mufflers. 3 catalytic mufflers, do to possible back pressure here I am with a great truck with bad engineers or money grabbing (?). So next, I hope that show will come that fixes problems with one loved truck. Put a mustang motor, trans & ecu. make my wife her ford adrenaline 2002. Problem FREE -
